[Qemu-discuss] VirtIORNG not working

we had some trouble with tomcat7 and the blocking /dev/random devices on KVM guests. So i’ve just tried to enable virtio-rng for the KVM guests like described here:

lsof /dev/random shows qemu - on the guest 
cat /sys/devices/virtual/misc/hw_random/rng_current
shows virtio.

But if i  cat /dev/hwrng nothing happens…. 

Any advice is very appreciated
